The VRE102C -- Voltage Reference -- is a commonly used Voltage Reference type in Power Management Integrated Circuitry (PMIC). It is a reliable, low power voltage reference source, with a typical input voltage range of 1.8V to 5.5V. This type of chip is widely used in various systems, including computer motherboards, smartphone battery, and other consumer-level electronics.

The VRE102C is a highly stable device with a temperature coefficient that ranges from -250 ppm/K to 7.5 ppm/K, so it is well-suited for long-term voltage reference uses where temperature fluctuations can be an issue. It has a typical input current of just 4 μA, which makes it low power and thus ideal for applications that require long runtimes with minimal power consumption. The output voltage level is adjustable up to 10 mV, so it can provide versatile and accurate voltage reference even in extreme operating conditions.

In addition to its temperature stability, the VRE102C has an adjustable output valtage accuracy of ±1% when operating at 15 V and its power line rejection ratio is 50 dB, ensuring good accuracy and stability even in the presence of power line noise. It also features an on chip reset circuit that can be used to control system reset during power up and power down, making it a good choice for use wherever reliable power management is a must.

The VRE102C works by providing a steady, predictable voltage reference to the system, which is then used as the basis for adjusting current or other power management requirements. For example, when used with a resistor divider, the VRE102C can provide a stable voltage reference for analog-to-digital conversions or for signalling a limit for switching devices. This allows for extremely accurate control of delicate systems and complex circuitry involving a variety of factors.

The VRE102C is available in a variety of packages, so it is easy to integrate into existing systems. It can be used in high-performance applications such as precision motor control and communications modulation, as well as low-cost consumer systems such as temperature monitors and timers. This makes the VRE102C an ideal choice for most any voltage refence application.
